The Horace Mann prep school — still trying to get past the sex abuse scandal uncovered in 2012 — has stripped the name of a former headmaster from its athletic field.

R. Inslee Clark was at the helm of the prestigious private school at the height of the decades-long abuse of 64 students by 22 faculty and staff.

The field will now be called Alumni Field.

Alumni include Roy Cohn, Jack Kerouac, Robert Caro and Eliot Spitzer.

Doug Henderson, another alumnus, who lobbied for the change and attended homecoming last weekend, told me, “It brought back a lot of memories. I spent six of the best years of my life at Horace Mann.”

“Having alumni vote on the renaming, and then having the school approve it, is a positive thing,” Henderson said. “This was the darkest of chapters in the lives of many. The renaming of the field is not a panacea, but a step in the right direction.”
